Kareem is working on a project for his manager. He has a few questions for a co-worker who he knows is knowledgeable on the subject. As they're discussing some of the topics, he gives the co-worker permissions to the resources so they can look at the information on their own. Which of the following access control methods does Kareem's company use?
a. DAC
b. RBAC
c. MAC
d. TSAC
Answer: RBAC
Explanation:
The access control methods that Kareem's company uses us the role based access control.
The Role-based access control (RBAC) simply means assigning permissions to users based on the role that such individual plays within an organization.
RBAC is a simple approach to access management and is typically less prone to error than in a scenario whereby permissions are assigned to users individually. Access rights are given to the workers based on what their job entails and what is needed and other information which isn't needed won't be accessible to them.
When in global configuration mode, which steps are necessary to edit an ip address on an Ethernet interface?
Answer:
I. You should enter interface configuration mode.
II. Configure the IP address and subnet mask.
Explanation:
A node refers to the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.
Some examples of network nodes are modem, hubs, computer, switches, phone and printers.
In Computer networking, network devices such as routers and switches are usually configured (programmed) through the use of specific network commands commonly referred to as configs e.g show int description, config terminal (config t), show IP address, etc.
In Cisco devices, there are five (5) main types of command modes;
1. Sub-interface configuration mode.
2. Interface configuration mode.
3. Line configuration mode.
4. Router configuration method.
5. Global configuration mode.
Global configuration mode is a configuration mode that avail network engineers and end users with the ability to modify or edit the running (global) system configuration of a networking device. Thus, any change effected at the global configuration mode will affect the network device as a whole.
In global configuration mode, the steps which are necessary to edit an ip address on an Ethernet interface include;
I. You should enter interface configuration mode using the "configure terminal" command.
II. Configure the IP address and subnet mask.
See an example below;
"Router(config-if)# IP address 192.168.1.2 255.255.255.0"

User-Defined Functions: Miles to track lapsOne lap around a standard high-school running track is exactly 0.25 miles. Define a function named MilesToLaps that takes a float as a parameter, representing the number of miles, and returns a float that represents the number of laps.Then, write a main program that takes a number of miles as an input, calls function MilesToLaps() to calculate the number of laps, and outputs the number of laps. Ex: If the inout is 1.5the output is 6.0 Ex: If the input is 2.2the output is 8.8 Your program should define and call a function Function Miles ToLaps(float userMiles) returns float userLaps 12 // Deine Milestola hert. 34 // Deine Minhert. Your code ust call llestola 5
Answer:
Explanation:
The following is written in Java. The MilesToLaps method creates a variable called laps and gives it the value of the input parameter miles divided by 0.25. Then it returns the variable laps to the user. In the main method a Scanner object was created and asks the user for the number of miles which are passed to the MilesToLaps method which returns the number of laps. This can be seen in the attached image below.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("How many miles?");
float miles = in.nextFloat();
System.out.println("This is " + MilesToLaps(miles) + " laps");
}
public static float MilesToLaps(float miles) {
float laps = (float) (miles / 0.25);
return laps;
}
}

Answer:
Digital computer
Explanation:
The computer that process data that are represented in the form of discrete values are called digital computer.
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Assume that the list will always contain fewer than 20 integers.
Ex: If the input is
5 50 60 140 200 75 100
the output is
50 60 75
Answer:
The program in Python is as follows:
num = int(input())
numList = []
for i in range(num+1):
numInput = int(input())
numList.append(numInput)
for i in range(len(numList)-1):
if numList[i] <= numList[-1]:
print(numList[i],end=" ")
Explanation:
This gets input for the number of integers
num = int(input())
This initializes an empty list
numList = []
This iterates through the number of integers and gets input for each
for i in range(num+1):
numInput = int(input())
The inputs including the threshold are appended to the list
numList.append(numInput)
This iterates through the list
for i in range(len(numList)-1):
All inputs less than or equal to the threshold are printed
if numList[i] <= numList[-1]:
print(numList[i],end=" ")
g Palindrome counting. Write a Python program stored in a file q3.py to calculate the number of occurrences of palindrome words and palindrome numbers in a sentence. Your program is case-insensitive, meaning that uppercase and lowercase of the same word should be considered the same. The program should print the palindromes sorted alphanumerically with their number of occurrences. Numbers must be printed first, and words must be printed nex
Answer:
The program is as follows:
sentence = input("Sentence: ")
numbers = []; words = []
for word in sentence.split():
if word.lower() == word[::-1].lower():
if word.isdigit() == False:
words.append(word)
else:
numbers.append(int(word))
words.sort(); numbers.sort()
print(numbers); print(words)
Explanation:
This gets input for sentence
sentence = input("Sentence: ")
This initializes two lists; one for numbers, the other for word palindromes
numbers = []; words = []
This iterates through each word of the sentence
for word in sentence.split():
This checks for palindromes
if word.lower() == word[::-1].lower():
If the current element is palindrome;
All word palindromes are added to word palindrome lists
if word.isdigit() == False:
words.append(word)
All number palindromes are added to number palindrome lists
else:
numbers.append(int(word))
This sorts both lists
words.sort(); numbers.sort()
This prints the sorted lists
print(numbers); print(words)

This criterion is linked to a Learning OutcomeCreate checkDuplicates method that receives an array of ints, and an int as parameters. It will return true if the int is found in the array, and false if the int is NOT found in the array. Call the checkDuplicates method from both the MegaMillionsLottery constructor, and the getUserPicks() method.
Answer:
Explanation:
The MegaMillions Lottery class was not provided and neither was the getUserPicks() method. Since they were not found online either, I have created the checkDuplicates method so that it works standalone. Therefore, you can simply call the method from wherever you need by pasting the call line where it needs to be called. A test case has been created in the main method so that you can see the method in action. The output is seen in the attached image below.
public static boolean checkDuplicate(int[] myArr, int element) {
for (int x : myArr) {
if (x == element) {
return true;
}
}
return false;
}

major characteristics of the bus in computer architecture
Answer:
A bus is characterized by the amount of information that can be transmitted at once. This amount, expressed in bits, corresponds to the number of physical lines over which data is sent simultaneously. A 32-wire ribbon cable can transmit 32 bits in parallel.
In computer architecture, a bus (related to the Latin “omnibus”, meaning “for all”) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.)
